.APLIGATION FILED SERT. 16. 1007.

HYDRAULIC A vertical partition, 14, extends downwardljT from the top, 9, and between the side walls, 5, and, 6, and the lower end of this partition projects in a plane below the upper edge ol. the short end, 12, ol the central partition, 1t). 'l his vertical cross partition, 14, has position spaced troni the end wall, 8, and beyond the inlet port, 13, in the side wall, 6, so as to lo'rni compartments, 15and, 16, at each side of the central partition. It will he understood that the cross-partition, 14, in the compartments, 15, and, 16, do not eX- tend to the bottoni, 4, and that a space, 17, is lett between the bottoni, and the lower edge of said cross partition, and that a-siini lar space is provided at both sides ol' the central partition.

Beyond 'the cross partition and about niidwajT between the ends, the easing or reoeptacle is provided at each side of the central longitudinal partition with another vertical cross partition,- 18. This latter partition extends vertically from the bottom, 4, with its upper edge, 19, terminating in a plane above the lower edge of the partition, 14

Between the central cross partition, 1S, and the outlet end, 7, of the receptacle the latter is provided with a crosswise partition, 20, exactly like the partition, 14, at the opposite end. This crosswise partition, like said partition, 111, extends downwardlv troni the top, 9, between the side walls, l,

and, 6, and the lower edge, 21, of this partition terminates in a horizontal plane below the plane of the edge, 19, of the central cross partition, 1S, and also below' the upper edge oi the short end, 11., of the central longitudinal partition.

An outlet opening or port, 22, is provided in the side wall, 5, adjacent the end wall, 7. and said port also has portion oi the side wall opposite the short end, 11, of the longitudinal partition, 10.

From the foregoing description it will be understood that the casing or receptacle is provided at each side of the central partition, 10, with passages and that each passage is provided with a plurality of vertical cross-wise partit-ions which extend respectively from the bottoni and top and that the ends of said partitions overlap so that the partitions that ext-end downward from the top will project in a plane below the upper edges of the partitions that extend up wardly 'from the bottoni. By this arrange-- nient of vertical partitions the. side passages are tortuous and any that enters the inlet port, 13, must flow beneath one partition and then up over another in seeking an out-` let through the valve or receptacle` it has hereinbei'ore lbeen explained that unpuriiied gas will be delivered to the reversing valve through the port, 13, and from the reversing' valve said unpuriiied gas is to be delivered to the center valve, 2, thence to position in. the Lrpperv erases the puriers, 1, and the purified gus is then carried back to the center r:ilve and revcrsing valve respectively, finally passing from the reversing valve bv port, 22. No nuit ter in which-of' the two dirt-lotions the gais is conveyed through the reversing vulve, it always enters the reversing valve b v' port, 125, and discharges through port, 22.

ln order to deliver the gas from the reversing valve to the center valve and lo pcrmit its ret-urn in a puriiind condition lironi the center valve to the reversing valve, two connections, 25, and, 24, are provided hetweenthe reversing valve and the center valve. Either of those connections may be employed to convejY the unpurilied gas to the center valve or to return the pnriiicd gas to the reversing valve but for the purj'ioses of illustration the connection, 2.3, will be presunied to be the one in the present instance to convey the unpuri'lied gas to the center valve while the'connection, 2i, vrill enable the purified gas to return to the reversing valve. These connections, in the present instance are shown on the top, .(1, ol' the valve casing or receptacle, and the connection, 23, is located on ,the inlet'side of the longitudinal partition and in a vertical plane between the cross-partitions, 14, and, 1S, while the con nection, 2l, has position on the opposite side of the ltmgitudinal partition and in. a vertrcal plane between the cross-parlitions, 18, and, 20.-

-It should be understood that the side walls, 5, and, 6, lit close against the vertical outer edges of the cross-partitions, 14, 18, and, 20, so that gas must poss beneath one of the partitions, 14, in seeking an outlet t'o the center valve.

ll: will thus be undorstoml that all of the walls and partitions described are stationary and immovable in the reversing valve. The operation of the valve will now he explained.

With the undcrstamling that thc unpuri` iied gas entering the port, 1.1i, is to be con-A veyed through the ciinneci'ion, 23, to the center valve which latter will direct it iin a desired course through ille puriiicrs, and that the purified in the present instance will be returned to the reversing valve Ylroni the center valve through coninctifni, 21, and discharged through port, 22, the operation will be. explained.`

For the purpose ot distinguishing the spaces on oppi'isite sides of the central pare tition, 10, the side ol' the valve where tln` gas enters will he. termed the inlet sidejvhile the opposite side will he termed the outlet side. and to distinguish the indivirilnril spares on said two sides those on the inlet side are drsignated by runnin-ale, 15, 25, 27, and, Ztl, while those on the outlet` side are designated by numerals, itl, 2li, 2l-1 and, 30.

The compartinentf` LES?, and, i?, at the in` let side of the valve will be supplied with a lll? the' outlet sidev of thevalve and at the were the level ofthe liquid in `thes e` compartments 'Will remain belowfthe` 'upper edge o'l l the cen-V` ter cross partition, 18,as lainly seen' in Fig 7.

thus provided betweenr compartments, 7, and, 29,.:to. prevent the passage of gas from opposite end'thereo'f'the 'cpmpartments, 16, .311.

center'I valve, 2. The center v alve will-be 26, will likewiseycontam suihcient liquidA to 'submerge the lower end of the partition', 14,"and thereby eHect aA liquid seal between these two compartments. It will thus be seen that two adjoining com artments at each end of the valve are liqui sealed while two other adjoinin compartments at opposite ends of the va vet'are'pnot liquid sealed,- thus fourcompartments 'are sealed and four are noty sealed. ,l

Thegas to bepuried will enter through port, 13, and be delivered into compartment, 15. It cannot pass through com 'artment, 16, because ofthe liquid sealin the ottomof the latter butit can pass beneath the partition, 14,int`o compartment, l25, because of the unsealedfspaee,l .17, between the two and 'consequentlyfthe -unpurified gas will flow into compartment, 25,'@As com artments, 27and, 29; .are sealed` thegasv to efpuried cannot pass in that vdirectionirom compart-v ment, 25,j"'and it must' therefore pass up through the conneetion, 23, and enter the adjusted to cause the yunpuriiedfgas to pass through the 'purifiers in any Well known manner and to then receive it in a purified condition from said purifiers. The kconnection, 24, of the reversing valve will be -made with fthat portion. of the center valve from which the puried gas would ordinarily be carried offend the purifiedgas will then pass through connection,'24, into' the improved reversing valve, being received into the comypartment, 28, at thefoutlet side of the valve As the purified gas cannot now pass through compartment, 26, because' of the seal be tween compartments, l26-, and, 16, it must=- flow' beneathrross partition, 20, 1nto compartment, 30, andthrough the outlet, 22, The puried gas after entering compartment 30, cannot pass over the short end, 11, of a center partition, .10, .and through com art-Y ment, 29, because the latter-is sealed' om compartment, 27, and has no outlet.

While the several compartments are sealed f as just described the unpuried gas must enter port', 13, and pass out through connec- 1 tion, 23, while the `purified gas must enter through connection, 24, and pass vout through port, 22.

Now suppose it is desirable as itV often 1s, to

reverse the iiowvof gas through the reversing `It will thus beseen t at aliqfuid scali-s..`

valvefthe centerfvalve. and uriiiers, the rechange inV either the center valve or the puri- `versal, .may be accomplis ed without va fiers, by simply altering the liquid seals in the reversing valve.. In eiecting a reversaly fof'jtheiiow throrgh the reversing valve the 'Doom art'r'nents,16, and,`26,.and, 27, and, 29, y

.will edrained of the liquid in any suitable manner such as by means 'of a pump and the compartments, 15, and,25, and, 28, and, 30, `W1ll then be supplied withy liquid. The inlet, 13, and outlet, 22, however remain the same.

The unpuriiiedgas will enter the inlet port, j'

through them but as connection, 2.4, to the center valve is open the unpurified gas will now passthrough this connection,.24, to the centervalve and then sent in a reverse direction through the latter and also through the purifiers. The connection, 23, now servesto lreturn the purified gas to the reversing valve,

whereas'before it directed the un uriiied gas to the 'center valve, andthe puriiied gas now entering through connection, 23, will pass from compartment, 27 beneath partition,

20, into compartment, 29, then over the shortvend, 11, of the center partition and across compartment, 30, to outlet, 22. The pure gas cannot now find outlet from compartment, 30, to compartment, 28, because of the liquid seal and consequently it 4musty flow through the outlet, 22,

It will thus be understood that bymerely changing the liquid from one set of compartments t'o another set a complete reversal of 'the flow of gas is eected through the centervalve and puriiiers Without making any alteration whatever-in the center valve.
